Description
Technical field
The present invention relates to the technical field of purifying waste water of current filtration treatment; Particularly a kind of multiple-effect carbon fiber filter to organic wastewater; The filtrate of said filter adopts spherical carbon fiber, can effectively handle the waste water that metallurgy, Coal Chemical Industry, electric power, petrochemical industry, papermaking, weaving, printing and dyeing and municipal administration etc. contain high-enriched organics or oil-containing.
Background technology
High concentrated organic wastewater generally is meant the waste water of COD more than 2000mg/L of being discharged by industries such as metallurgy, Coal Chemical Industry, petrochemical industry, papermaking, leather and food.Contain a large amount of organic pollutions such as phenol cyanogen, oil, biphenyl, pyridine, indoles and quinoline in these waste water, pollute and look for height, character is highly stable, and organic matter and color removal difficulty are if directly discharging can cause severe contamination.Oily waste water is mainly derived from industrial departments such as petrochemical industry, iron and steel, Coal Chemical Industry, machining.Oil pollution material in the waste water, except that the relative density of tar heavy oil be more than 1.1, remaining relative density is all less than 1.Oily substance exists with three kinds of states in waste water usually.(1) floating oiling, oil droplet size is easy to from waste water, separate greater than 100 μ m.(2) dispersed oil, oil droplet size suspends in water between 10-100 μ m.(3) oil emulsion, oil droplet size are difficult for from waste water, separating less than 10 μ m.Because oil concentration is widely different in the waste water that different industrial departments are discharged; Like the waste water that produces in the oil refining process; Oil content is about 150-1000mg/L, and tar content is about 500-800mg/L in the coking chemical waste water, and the tar content that gas generating station is discharged in the waste water can reach 2000-3000mg/L.Therefore, the improvement of oily waste water should at first utilize oil interceptor, skimming or heavy oil, and treatment effeciency is 60%-80%, oil content is about 100-200mg/L in the water outlet; Oil emulsion in the waste water and dispersed oil are then more hard to manage.The waste water that contains high-enriched organics and oil-containing at present generally adopts the two-level processing system of preliminary treatment+advanced treating to handle; Wherein advanced treating adopts two membrane method treating process of " ultrafiltration+counter-infiltration "; Usually, film also is provided with pretreating process before handling; Multi-medium filtering device, the fiber ball filtering devices etc. of adopting more, but existing filter can't be removed the COD in the waste water in filter process, and also very low to the clearance of the oil in the waste water; Go out water quality standard and be difficult to reach the into water quality requirement of film, cause that the reverse osmosis membrane cleaning frequency is high, service life low problem.The mechanical agitation that the multi-medium filtering device runs in sand, the fiber ball filtering device causes damage to fiber filtering, and reduced the service life of existing fiber filtering, occurs stopping up the problem of membrane channels simultaneously.Therefore combine production practices; Developing a kind of desirable required new and effective filter of wastewater treatment that contains high-enriched organics and oil-containing to metallurgy, Coal Chemical Industry, electric power, petrochemical industry, papermaking, weaving, printing and dyeing and municipal administration etc. is an important topic in the industrial environment improvement work, also is characteristics of the present invention.
The subject matter that existing fiber ball filtering device exists: retaining power is big, filtering accuracy is high, filtrate is prone to backwash and regeneration and backwash water yield small loss and other features though existing fiber ball filtering device has; But existing fiber ball filtering device is prone to fiber filtering is caused mechanical damage, thereby causes reduce the service life of existing fiber filtering.Existing simultaneously fiber ball filtering device can't be removed the COD in the waste water in filter process, also very low to the clearance of the oil in the waste water, and goes out water quality standard and be difficult to reach the into water quality requirement of film, cause that the reverse osmosis membrane cleaning frequency is high, service life low problem.
Summary of the invention
The present invention is directed to the defective or the deficiency that exist in the prior art; A kind of multiple-effect carbon fiber filter to organic wastewater is provided; The filtrate of said filter adopts spherical carbon fiber, can effectively handle the waste water that metallurgy, Coal Chemical Industry, electric power, petrochemical industry, papermaking, weaving, printing and dyeing and municipal administration etc. contain high-enriched organics and oil-containing.
